Germany backed their own H&K alternative. and the two weapons, the SS190 round, and a few other specialty ammo variants such as the L191 tracer and the SB193 subsonic round were submitted to NATO for testing and evaluation. The P90 was then modified slightly to feed the SS190 reliably. The shorter length allowed the round to feed more reliably in the FN Five-seveN handgun that was also in development at the time. This SS190 would go on to become the standard 5.7×28 round. NIJ Ballistic Threat Level Chart for Body Armorįurther development led to a round with a slightly shorter, but heavier projectile that still reached speeds of 2,350ft/s out of the P90. So, having a lightweight and lightly-recoiling round that could defeat this type of body armor was attractive to many potential adopters from various militaries and police agencies. Out of the P90, the round was capable of penetrating Level IIIA ballistic armor at 200 meters. It used a 23-grain projectile moving at 2,800ft/s when fired out of the 10.4-inch barrel of the FN P90 (developed at the same time). In 1990, FN completed development on the first 5.7 round, designated the SS90.

The goal was to create a round with better range, accuracy, and terminal performance than the 9mm. The FN 5.7x28mm round was originally created as part of an attempt by NATO to replace the 9x19mm round that was (and is) the standard sidearm round for most of the Western military and police forces.

Five-SeveN with 5.7x28mm Ammo and 20 Round Magazine It’s also deceptively light at just 1.6 pounds loaded. Instead, it uses an internal pre-cocked hammer design. The gun is not striker-fired as many would assume.

Like the P90, the Five-seveN is a lightweight, polymer-framed gun that has a high capacity for its size with 20 rounds on tap in a Glock 17-sized frame. The FN Five-seveN is the companion sidearm meant to go with the P90.ĭeveloped by FN early on in the life of the cartridge, this handgun actually caused significant changes to be made to the overall design and dimensions of the round - particularly so it would feed reliably in a handgun.
